    [SPARK-19033][CORE] Add admin acls for history server · 4a4c3dc9
    jerryshao authored
    ## What changes were proposed in this pull request?
    
    Current HistoryServer's ACLs is derived from application event-log, which means the newly changed ACLs cannot be applied to the old data, this will become a problem where newly added admin cannot access the old application history UI, only the new application can be affected.
    
    So here propose to add admin ACLs for history server, any configured user/group could have the view access to all the applications, while the view ACLs derived from application run-time still take effect.
    
    ## How was this patch tested?
    
    Unit test added.

    Closes #16470 from jerryshao/SPARK-19033.
